Hi, I installed snow leopard on my machine and my ruby on rails project stopped working… When I tried script/server I this error Booting WEBrick =\> Rails 2.3.3 application starting on [http://0.0.0.0:3000](http://0.0.0.0:3000) /Library/Ruby/Gems/1.8/gems/activerecord-2.3.3/lib/active\_record/connection\_adapters/abstract/connection\_specification.rb:76:in `establish_connection': Please install the postgresql adapter: `gem install activerecord-postgresql-adapter`(dlopen(/Library/Ruby/Gems/1.8/gems/pg-0.8.0/lib/pg.bundle, 9): no suitable image found.

Do you still get the same error when trying to start script/server, or did it change? Because the ARCHFLAGS setting should have worked indeed. If it’s still the same, I would try to uninstall the pg gem completely first before reinstalling it the same way.
